You receive an "A required.DLL file, snmpapi.dll, was not found" error message when you try to run Zoo Tycoon 2 for the first time (909533)

RESOLUTION

To resolve this issue, copy the Snmpapi.dll file from the Drive:\Windows\Servicepackfiles\I386 folder to the Drive:\Windows folder. To do this, follow these steps:

1. Click Start, and then click Search.
2. In the Search Companion dialog box, click All files and folders.
3. In the All or part of the file name box, type snmpapi.dll.
4. In the Look in box, click My Documents, and then click Search. The search results show the Snmpapi.dll file in two locations on the computer.
